The device finds its largest usein'conn'ec- 1 tion with the securing of aninvalid cot,

stretcher, or similar support, within anambulance and providesfo'r'a speedyadpistment and the simultaneous locking of the same in position from a point adjacentthe rearwardend of such ambulance.

.Heretofore clamping devices for invalid cots have been provided, but such devices in most instances requ re individual ad ust- .ment to the frame members of the cot and considerable ,time is "consumed n safely positioning the invalid within the ambulance before said vehicle'can get under way to a hospital.

As is clearly.shown iniFigi l ofthe draw-,

ing, a movable cot l for inva'lid s is provided, with a tubular metal framework having p irs'ol uprightframe embersaa, at the The principal objectof the present inven; tion is to providea device which-will serve,

plurality of notches 8 adjacent its lower end to'engage a cross bar'I9 secured to'the an I Ataf spaced distance above the fi'oor'10 I of the 'ainbulancefor' other compartment within which said cot-is to be positioned,

there are secured toflthe wall 11, a plurality of brackets shownfas having circular bases -12and upwardly turned arms '13., The outer ends of said bracket jarms terminate, in

sleeves 140i a size toreceive altubular supporting rodf15', and ,rigidly -hold the same upper side ofeach' 'of said sleeves. Atian intermediate point of said supporting rod. I

ing bar-abellcra'nk lever; 18 is pivotally secured to-a pivot support 19jfixed-to said supportingrod. q r

f On said supporting rodatapoint between said bellcrank lever and said pivoted cross bar a slidable sleeve '21 is provided, said sleevecarrying an integral cllampinghook upon its outer side and having' a 1m:

jectinglstupl its innergsida. I pen the underside ofsaid sleeve acpair of ears 24 project downwardly and are connected by means of a link 25 with the adjacent end of the bell crank lever to which" it is secured by means of apivotpin .26. ,Alink 27 is journaled upon said stud 23 and has its opposite end 28 pivotallywconnected with the upper end 01" the cross arm l'ii The hook 22 vof said sleeve is preferably covered with cushio as rubberjia nd said 'ookjis directed for- Iwar.dly toward said pivoted cross arm. A second sleeve .31 is engaged upon the supporting rod ,up on t hei opposite side of the cross varm l7 "'fro nrthe first described sleeve 21; and; earricsa siinilar hook-.32 and studfi-S. A' link 34 isfpivotally mounted uponsaid ,stud and' has its, opposite; end 35 pivotally ctiiinectedwith,the 'lower end of said cross jarnifhSaid ho ok 32 similarly lined on its under sidefwith rubber or suitable cushioningvmaterial andis turned in a direction @opposite to the hook 22 and also ,f acinglthepivoted cross arm. v i In the form of construction shown Figs. 6 to 9, inclusive, the cot holdingmechanism is enclosed ,within a, casing 41 ot channel- 'like.form. Thepositionofthe cross arm is clearly shown in Sand 8 wherein a '39 projectsinwardly from the central Pa t es Qf s de ude as ess er asaprvot the cros s arm 43 which is o ur naled,v centrally thereon. {The ends of the cross arm are connected by means of as links .44, 45', with pins e6, 47 secured to SUI .jplates e8, 4t9, ,slidin'gly mounted upon the seam sa d eas s- S id Pi r j inwardly through longitudinal slots 51', formed insaid casing, asis shown in Fig.

"7, and the links are journ aled upon the in nerends ofsaid pins. Qutside o'fthe slots 15 add iticna l longitudinal slots ,52 are pros vided andjheaded studs 53,Q5 4, are secured vto sai djrespective"plates with their 7 shanks ,lslid n gly engaged within said slots; The outer. ends offsaid plates are provided with v i hpolgs 5 5; 56, which are directedinwardly T 57 is toward, each? other. I rrd'l acent. one-fiend qfthe casing a bracket provided with a pivot pin .58 upon which a bell crank lever 59 is. mounted. LSaid bell crank lever is provided with a handleffidat end of itslonger ar m and isl'pivotally[connected withjthe stud 54' of thejladjacent sliding plate gtfl-bymeans of a li-iikii l connected at itsother end with the sherter ,arnr62tof' the bell crank lever.

As is more clearly shown 9, the casing is adapted to be secured to a side an: 63hr mea se ara angle ack ,.,6fl. Each o'fjsaid angle brackets has one "end rivetedto the under sideof the clrz tnnelshaped casing an d has its free end turned [d nwar y s9 th f ma be n a e V hind a suitable shaped strap 65, the ends of ingmatverial 2 Such I which are firmly secured to the side wall upon which the casing is supported.

lVhen the device is mounted in an ambulance the bell crank lever is preferably disposed towardthe rearward portion thereof, with the-handle 35 at the lower end tl ereotlocatedata convenient position for the use of the attendant standing upon the ,stepsiatthe rearward end of the ambulance.

The, operation oft-he clevice it isbelieved will be apparent from tl e description of. its construction. The cot or v stretcher carrying the invalid ,is rolled or -carried 'to a position agent the a mb ulance is then ifte t t 6, 0 lev 9 th ambu a andimovrgd;inside o said vehicle. As the cot passes int- 0 fliorward end ot the vehicle' the handleof the bell'ljcran k lever is .li'ftedgandthe hooks on sliding sleeves .thereofare thus drawn apart. When the rcloselyitogether with the icotlcentered'and clamped betweenthe ho olrsfthereof. As the bell crank leverreaches its'lowermo'stposition the pivot pin 26 connecting theshorter 6 arm of said lever with ,the link 25'; will ,be drawn, to a position I past dead center and thus will automatically serve to lock the invalidcot against release through pres-- u ror the ampi h ks- NVhile the cot illustrated is of the conventional type of wheeled hospital cot, itiis 010-.

,vious that thedevice will ge era clamp and positionany-type of cot, stretcher, or similar support for an invalid'which i's supported upon a framework "having upright "s ppo t n m mb 'llhettact that the device, has .been shown and described in connectio nlwith an ambulance is not intended to in any way restrict the applic ation of the device to said use,;'inasmuch as it is of much advantage for-fuse upon shipboard and may also be found useful in certain hospital wards where it is desired that a wheeled cot be free' from 7 danger of being shifted from position under lit) of a cot-or stretcher of the type described, 1

and temporary wards in hospitals or'sick bays on shipboardmay-beestablished without rendering diflicult therestoration of suc-h compartments to their customary use.

Other modes of applying the principle I therefore particularly point out and distinctly claim as my invention':

cured to a fixed support for rigidly clampmg an invalid cot against mot1on,comprising a support adapted to be attached to side wall, a pair ofclampsslidably mountedthereon, links connecting said clamps, and lever-actuated meansfor drawing said clamps toward each other and automatically locking the same against separation. v V v 2.
